Wagner Paint eater was working fine until it grabbed my tee shirt. I got it shut off and unwrapped my shirt. It still runs but when I put it to the wood and it meets resistance the sanding disc stops turning. I guess something internal got stripped and it is not grabbing to turn the disc. Can it be fixed?

SOURCE: Wagner paint crew won't build pressure or shut off.

1. Does it pump paint in PRIME position. If yes, then the outlet valve assembly may be stuck or bad.

2. If it won't pump paint in the PRIME position, the inlet valve may be stuck, just poke your finger down the inlet hole (machine off) . It is spring loaded and should move about an 1/8".

3. The worst option is the pump piston if froze. To check: remove the plastic hopper assembly, comes off with about 4 screws from underneath. The whole thing just pulls off. Now you can see the inlet assembly with two O rings. Use the white plastic hex shaped tool comes with the spray, and stuck on the lower base of the unit. Unscrew the inlet assembly. If clean enough, you can see the end of the piston. It's about a 1/4" diameter. Turn the machine on for a moment and you shoud see the piston move back on forth. If it doesn't the piston is froze. Good Luck with that.

SOURCE: why does my gun keep spitting

Spitting is usually caused by not filtering the paint through a strainer (made for the purpose by the paint manufacturer). The paint debris blocks the paint for just a moment, then spits it out. Easy fix!
